It absolutely looms over us… all of us, from admin to teacher to janitor to student.
We have regular lockdown drills in which they try and trick us / scare us into opening the door or making sound from the rooms… because that is necessary and people always screw up. We have to have matter of fact conversations with kids about what to do if they’re trapped outside the room, about if a shooter starts coming through the door, and I include about how if on a random day a fire alarm goes off unexpectedly, they will not exit the room until I do and we will exit last on our hallway. When I walk down a hallway, I habitually look at every door I pass to the outside to see if it is truly closed and locked. There are over 60 external doors at my school of over 2000 students. These high schoolers will rig the door to not truly shut so they can sneak out and back in. We have to tell them almost weekly to “ignore the door” because at random times a plain clothed sheriffs deputy will come to the school to do security checks and knock on an external door to see if they can get in. Sometimes a student opens it, sometimes they find a rigged door. I have honestly never heard of a time where one came and wasn’t able to get in. Once in, they’ll walk around the school until someone stops them and asks where their ID is. They typically make it between 30-60 minutes.
Sorry for the rant. But yes, it’s ever looming, and yes, we all have it in the backs of our minds. Can’t tell you how many times I’ve stopped dead in my tracks in a crowded hallway at class change because a student suddenly stops walking, puts their book back on the ground and reaches inside it. It’s there like your shadow and it sucks and there’s no amount of “well the statistics say…” that is gonna paper over that.
